A method of screening a composition for insect control activity, comprising: providing insect cells expressing at least one receptor chosen from tyramine receptor, Or83b olfactory receptor, and Or43a olfactory receptor; adding said composition to the cells; measuring the binding affinity of said composition to the tyramine receptor or the Or43a receptor or to any two of the tyramine receptor, the Or43a receptor, and the Or83b receptor, or to all three receptors; and selecting compositions having an affinity for the receptor or receptors.
一种筛选昆虫控制活性组合物的方法,包括提供表达至少一种受体(选自
酪胺受体、Or83b嗅觉受体和Or43a嗅觉受体)的昆虫细胞;向细胞中添加所述组合物;测量所述组合物与
酪胺受体或Or43a受体或与
酪胺受体、Or43a受体和Or83b受体中的任意两种受体或与所有三种受体的结合亲和力;以及筛选出与一种或多种受体具有亲和力的组合物。
